Added setup.py

[puterleat]

This would be simple to add to pypi now, and I think the name scholar is not taken there.

Only major change is renaming scholar.py to scholar because of setup.py weirdness about script names which match module names. Perhaps we should suggest creating an alias from scholar.py to scholar to preserve backward compatibility?

btw - to test can run

pip install -e git+https://github.com/puterleat/scholar.py.git#egg=scholar
